if you search for a sata data cable. that should get you what you need its not really a cable you can build yourself
oh your refering to the sata power, j12? its called a jst 2pin it can be aquired from lots of places.. ebay is one such place..
So this is about the only cable I can find that would interface a SATA power to a JST connector, and it's nifty that it also has a SATA interface on the same connector, and it's a right-angle connector. The drawback is the minimum order is 300 pcs, so that puts it out of reach of most folks unless the folks behind Udoo get a batch of these and re-sale them here on the site as an added accessory. http://sshly.en.alibaba.com/product/357 ... _4PIN.html
